Battlefield 4′s third downloadable expansion pack, Naval Strike, has been fully detailed following news that the game’s second pack, Second Assault, will be available next week for Battlefield 4 Premium members – this time, it’s all about non-stop warfare on the high seas!

Battlefield 4: Naval Strike will include four new maps, all set out in the South China Sea and making use of the game’s impressive dynamic water-based battles with skirmishes taking place in and around crashed passenger planes, fishing villages and at least one tropical island, plus more:

“Drop a submarine on your foes as you infiltrate a naval base or rush between shipping docks and rocky islands on the massive Wave Breaker map,” writes EA. “Wage war across stormy seas in the largest ocean stretch in a Battlefield map yet with Nansha Strike. Storm an abandoned cliff-side resort, or get lost in the breathtaking vistas in Operation Mortar.”
